"What's a lesson you learned the hard way?"
"It was in elementary school. I didn't read and I didn't participate. I was uninterested. But as I've gotten older, I've realized how important it is to participate, engage, read, and learn. I read often now. I've tried to impress that on my kids and my grandchildren: they should raise their hand in class and answer questions. I try to read books around them now. I hope that if they see me reading a book, they'll pick one up, too."
